Determine the temperature at which there is 1 percent probability that an energy state is empty.
Assume that the Fermi energy level for a particular material is 6.25 \mathrm{eV} and that the electrons in this material follow the Fermi-Dirac distribution function. Calculate the temperature at which there is a 1 percent probability that a state 0.30 \mathrm{eV} below the Fermi energy level will not contain an electron.
